Section 1 Seats and Restraint System

{CAUTION:
Sitting in a reclined position when your vehicle is
in motion can be dangerous. Even if you buckle
up, your safety belts cannot do their job when you
are reclined like this.
The shoulder belt cannot do its job. In a crash,
you could go into it, receiving neck or other
injuries.
The lap belt cannot do its job either. In a crash the
belt could go up over your abdomen. The belt
forces would be there, not at your pelvic bones.
This could cause serious internal injuries.
For proper protection when the vehicle is in
motion, have the seatback upright. Then sit well
back in the seat and wear your safety belt
properly.
Manual Reclining Seatbacks
On seats with manual reclining seatbacks, the lever
used to operate them is located on the outboard side of
the seat(s).
To recline the seatback:
1. Lift the recline lever.
2. Move the seatback to the desired position, then
release the lever to lock the seatback in place.
3. Push and pull on the seatback to make sure it is
locked.
1-11

Center Seat
Your vehicle may have a front center seat. The seatback
doubles as an armrest and cupholder/storage area for
the driver and passenger when the center seat is
not used. Do not use it as a seating position when the
seatback is folded down.
Rear Seats
Rear Seat Operation
The rear seat is a 60/40 split bench seat that can be
folded to give you more cargo space and access to the
folding midgate. SeeMidgate
®on page 2-13for
more information on operation of the folding midgate.To fold either side of the seat do the following:
1. Push the rear seat head restraints all the
way down.
2. Pull the seat loop
located where the
seatback and
seat cushion meet. The
seat cushion will
release and allow you
to tilt it toward the
front of the vehicle.
Notice:Folding a rear seat with the safety belts
still fastened may cause damage to the seat or the
safety belts. Always unbuckle the safety belts
and return them to their normal stowed position
before folding a rear seat.
